Struct Signal 

pub struct Signal<T> { /* private fields */ }

A reactive value, shared by reference.

Cloning is cheap (shared Rc): a copy points to the same value, so a signal passed to the timeline and a signal inside a shape are one object.

Implementations

impl<T: Tweenable> Signal<T>

pub fn new(value: T) -> Self

Creates a signal with an initial value.

pub fn get(&self) -> T

The current value (a clone).

pub fn set(&self, value: T)

Writes the value immediately.

pub fn tween_to(&self, to: T, duration: f64, easing: Easing) -> Action

Creates an animation from the current value to to over duration seconds.

The start value is captured at the moment the animation runs on the timeline, so consecutive tweens neatly “pick up” from each other.

pub fn step_to(&self, to: T) -> Action

An instant value set as a timeline element (a zero-length tween).

Trait Implementations

impl<T> Clone for Signal<T>

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
